It.s more like a humming sound....Using the stock 7 cell hump..seems to get louder when adjusting steering trim....then goes away....Called Traxxas,,,they said it was the servo and it's normal...not sure I buy that

Did you ever figure out what this noise is? Mine is doing the same. 1 day old and my servo was trashed. Traxxas was good enough to send another quickly. I replaced it and in about 2 minutes the new servo was stripped. It's like it's always trying to turn the servo.

You better call them back and find out the root cause of the problem. I'm still using the original servo for 10 months now and it still works fine. I run it every day and twice on weekend days, mostly full bore on/off around a short oval track with my Doberman in hot pursuit. I'm also running tractor tires on dirt on 3.2 wheels with 17 mm hexes, so it does get a workout and never has been a problem.
